y PRAIRIE ISLAND NUCLEAR GENERATING PLANT-UNITS 1 & 2 NORTHERN STATES POWER COMPANY MASONRY WALL DESIGN One Hundred and Eighty Day Response to IE Bulletin 80-11 1.0 GENERAL 1.1 The report presents Northern State Power Company's one hundred and eighty (180) day response to NRC's IE Bulletin No. 80-11 for Masonry Wall Design for Prairie Island Nuclear Generating Plants Units 1 & 2.
1.2 All accessible Masonry Walls in the plant covered by the bulletin were physically surveyed in the month of June, 80 by engineering teams con-sisting of various disciplines.
The walls which were inaccessible during this survey were inspected in the month of September,1980.
O 1.3 A sixty (60) day response to the bulletin was submitted in July,1980 V
on the basis of the June Survey, and the detailed study of engineering drawings and material and construction specifications written for the project.
1.4 The sixty day report identified all masonry walls at the plant which are in the proximity to or have attachments from the safety related piping or equipment such that the wall failure could affect a safety related system.
A re-evaluation Acceptance Criteria for the walls was described in the sixty day report.
1.5 The report is updated to include walls inspected in the month of September,1980. One hundred and twenty one walls were identified as safety related walls per IE Bulletin 80-11. Typographical errors of the earlier version are also corrected.
1.6 The revised sixty day report is included as Attachment A.
1.7 The design adequacy of supports attached to the masonry walls with cinch anchors or thru bolts is not included in this scope of work.
The safety of the wall, however, is examined for the loads transmitted by the supports.
1.8 A brief discussion of the walls including the functions M the walls, their material and construction requirements, inspection and quality assurance programs, support conditions and reinforcement detail are oQ described in Section 2 of this report.

,V 1.9 The results of the re-evaluation of the masonry walls are discussed in Section 3 of the report.
2.0 DESCRIPTION
OF THE WALLS 2.1 Function of the Walls 2.1.1 Concrete Masonry Walls of Prairie Island Plant, as discussed in Attachment A were designed as partition walls or as shield walls.
Ducts, piping, electrical conduits or boxes were pemitted on the wall only if their weights were negligible.
Penetrations in the walls for pipes and ducts were pemitted.
In most cases, pipe sleeves were provided in the block walls for the penetra-tions.
2.2 Material and Construction of the Walls 2.2.1 All block walls of the plant were constructed with material and construction cpecifications describec in Attachment A.
2.3 Quality Control and Inspection of the Walls G
2.3.1 Adequate inspection and quality control measures were taken to
/d insure that good engineering cor.struction practices were used for the block walls.
Inspection and Quality Assurance records obtained from the plant QA were reviewed.
No discrepancies in the material and/or con-struction practices were found.
2.3.2 Attachment B provides details of the field inspection procedures.
The inspection of the materials and workmanship assured that no significant voids or other weaknesses in any mortar grout were permitted, and the reinforcing steel was per structural drawings.
2.3.3 The masor.ry blocks were tested by an independent laboratory for compressive strength.
All tests indicated that the blocks met or exceeded the specified minimum strength values.
2.3.4 Quality control and rigorous construction inspection was exer-cised at the time of the preparation of the mortar and laying of the blocks. The mortar and grout specimens were tested for 7 day and 28 day strengths. The test values exceeded minimum values spec.ified in the code.
2.4 Reinforcement Details and Boundary Conditions 2.4.1 The block walls are reinforced both vertically and horizontally.
O The horizontal reinforcement consists of Dur-0-Wall. Wnerever V
a discontinuity of the reinforcement resulted due to an opening such as a door-way, additional horizontal and vertical reinforce-ment was provided around the opening.

Page 3 2.4.2 In case of multi wythe walls individual wythes are connected by the use of reinforcement ties.
The space between the wythes was filled with grout. For twenty four inches thick walls, mortar joint was provided between two twelve inches thick blocks.
2.4.3 Some walls are hollow reinforced and others are solid grouted walls.
2.4.4 The walls in most cases are connected to the floor with dowels.
The first course of blocks were laid after a layer of mortar was placed on the floor.
2.4.5 The top edge of the partition walls are supported in the trans-verse direction only.
One inch space was maintained between the wall and the ceiling.
The simple supports for the vertical edges of the walls were provided by the fasteners.
2.4.6 Boundary conditions and reinforcement details for the safety related walls as they now exist are shown in sketches of Attachment C.
3.0 RE-EVALUATION OF THE WALLS 3.1 The walls identified as Safety Related Walls in Attachment A were re-analyzed per Re-Evaluation Acceptance Criteria presented in the Attach-ment A.
3.2 The transverse earthquake forces acting on the walls were computed by the spectral approach.
The natural frequencies of the walls were com-puted and the spectral acceleration selected for appropriate damping values.
3.2.1 Two percent damping was used when the wallwas assumed not to be cracked for both operation and design basis earthquakes.
3.2.2 Five percent damping was used when the wall was assumed to crack for both operation and design basis earthquakes.
3.2.3 A conservative spectral acceleration was selected for the wall by varying the computed fundamental frequency by ten percent.
Ten percent margin was considered adequate to account for the variability of material and construction.
3.2.4 A peak acceleration value was selected as a representative acceleration for the wall when the fundamental period was on the steep gradient of an acceleration vs period curve for the floor.
/^'T
.V, 3.2.5 Transverse force acting on the wall was computed by multiplying the mass per unit area of the wall and the selected acceleration.
The force was conservatively considered to be constant for the entin! wall area.

\\s Page 4 3.2.6 The loads of the equipment and piping attached on the wall were conservatively estimated to account for the seismic response of the system.
3.2.7 The influence of the openings in the wall on the natural period of vibration of the wall was found to be inconsequential.
3.2.8 Earthquake induced differential floor movements do not exert any inplane (longitudinal) forces on the walls. This is due to the one inch gap between the ceiling and the top of the wall.
3.2.9 The wall was considered safe when it could support all loads either as a beam or as a plate.
3.2.10 The walls were considered unreinforced when the stresses in
- duced on the walls were smaller than those allowed for tension on the block walls.
3.2.11 Most of the safety related walls have successfully met the re-evaluation criteria of Attachment A.
The walls which did not meet the criteria are listed in Table I.
d 3.2.12 The walls requiring modifications are grouped in two sets.
Set one consists of the walls for which corrective action is already identified and the physical modifications are under way.
The second set consists of walls for which corrective measures are being engineered.
3.2.13 The walls requiring modifications are safe under normal and accidental loads imposed upon them.
In all cases the failure of the walls is due to the postulated Earthquake loads.
4.0 OPERABILITY CRITERIA 4.1 The objective is to physically modify all walls which fail to meet the acceptance criteria as soon as practicable.
Hence, no discussion is presented with regard to the mode of failure of the walls and its significance on the operational safety of equipment and/or piping attached to the walls or located in its proximity.
5.0 FIELD MODIFICATIONS 5.1 Details of Modifications 5.1.1 Ninety seven of the one hundred and twenty one safety related masonry walls met the re-evaluation criteria. Twenty four walls did not meet the criteria and need field mudifications.

One Hundred and Eighty Day Response to IE Bulletin 11 21-7450-280 Page 5 5.1.3 The modifications for the walls consist of (a) changing existing free edge condition of the wall to a simply supported edge condition in the transverse direction, and/or (b) introducing additional supports to reduce the span.
5.1.4 The simple support conditions for the walls, where required, will be obtained by attaching steel members to the ceiling and/or side walls and columns on both sides of the masonry wall.
A minimum gap of 1/8" shall be maintained between the wall and supporting steel.
This gap will permit free motion of the support in the plane of the wall.
5.1.5 The reduction in the span will be obtained, where required, by installing a structural member on one side of the wall at suitable intermediate locations.
The member will be connected to the floor, ceiling and block wall.
The connection of the structural member to the ceiling will allow for deflection of the' ceiling.

PRAIRIE ISLAND NUCLEAR GENERATING PLANT UNITS 1 & 2 NORTHERN STATES POWER COMPANY MASONRY WALL DESIG'1 RESPONSE TO BULLETIN 80-11
1.0 INTRODUCTION
1.1 The raport presents Northern States Power Company's sixty day response to NRC's IE Bulletin No. 80-11 for Masonry Wall Design for Prairie Island Nuclear Generating Plants Units 1 and 2.
1.2 Our review of the bulletin and Trojan Nuclear Plant's LER No. 79-15 indicates that the structural integrity of Concrete Masonry Walls is questioned by the Nuclear Regulatory Commission because:
1.2.1 Certain high energy and large diameter (greater than 2 l/2 inches) pipes are supported on the block walls as a routine design pro-cedure without adequate engineering review of the walls.
1.2.2 Use of non-conservative design criteria for the allowable inter-face shear and tensile stresses used for Double Wythe Concrete Masonry Walls.
1.2.3 Problems of interpretation of masonry wall code. The difficul-ties in the interpretations are attributable to the fact that the design loads and the load combinations are factored loads based on ultimate strength method of design whereas the allowable stresses in the code are based on working stress design method.
2.0 DESIGN PHILOSOPHY 2.1 The review of design calculations and final safety analysis report for the Prairie Island Nuclear Generating Plant indicates that the concrete block walls do not fall into the same design philosophy as the design of masonry walls of Trojan Nuclear Plant which instigated the bulletin.
2.2 Concrete masonry walls of Prairie Island Plant were generally designed as partition walls or as shield walls.
Penetrations, however, were permitted in the masonry walls for pipes and ducts.
2.3 Attachments of both safety and nonsafety related equipment, ducts, pip-ing, electrical conduits, etc., were permitted only if their weights were insignificant.
2.4 The design of the plant was based on the working stress design method
[v) and therefore, no ambiguity in interpreting the code to establish the s
allowable design stresses existed. The walls were designed on the basis of Uniform Building Code of 1967.

t FLUOR POWER SERVICEO,1NC.
RESP 0itSE TO IE BULLETIN 11 21-7450-280 Page 2 2.5 Concrete masonry walls of the hydrogen room and probably those around the elevator shaft were designed as shear walls.
3.0 TYPE OF CONSTRUCTION 3.1 The construction and materials for concrete masonry walls in the plant were classified as Quality Assurance type I except for walls in the administration building, service building and around toilet and sundry facilities which were classified as type III.
3.2 Inspection and Quality Assurance records for these walls exist at the plant. They will be reviewed prior to the detailed analysis of the wall s.
- 3. 3 The plant has approximately 275 masonry walls. Some of these are single wythe walls and others are double wythe walls. The walls are reinforced vertically and horizontally.
In case of double wythe walls of 18", 30",
42" and 48 inchas thickness, the two wythes are interconnected with lateral +.ies per Unifonn Building Code,1967.
4.0 IDENTIFICATION OF WALLS 4.1 IE Bulletin 80-11 requires identification of all masonry walls at the plant which are in proximity to or have attachments from the safety-related piping or equipment such that the wall failure could affect a safety related system. This phase of work, except for inaccessible walls, is completed, and the walls are identified in Table 2 through 5.
4.2 The identification procedure consisted of sequential numbering of each masonry wall in the Class I area of the plant.
The areas excluded from the consideration are the radwaste building, administration building, security or guard house and chlorine building. The walls in these buildings are not identified as they are not considered safety Class I areas.
The walls in the reactor building have not been identified be-cause of inaccessibility of the area at this time. Walls in the reactor building will be identified when the area becomes accessible, during plant outage.
4.3 The drawings were giv.n to various disciplines (Mechanical engineering, Piping engineering, Electrical and Instrumentation and Control engi-neering, Structural engineering)to identify walls with any safety re-lated system as defined in 4.1.
4.4 Field engineering survey of all numbered walls was conducted.
4.5 The objective of the survey was:
d 4.5.1 To verify, to the extent possible, that all walls identified as having no safety related equipment in the vicinity indeed do not have any safety related equipment in the vicinity.

_ (U 4.5.2 To record and to identify all safety and non-safety related equipment in the vicinity of the safety related walls, and to estimate loads transferred to the walls.
4.6 Two engineering teams were sent for the field survey.
Each team con-tained experienced staff from the foUowing four engineering disciplines; electrical, instrumentation and controls, mechanical and structural engineering. The teams were under supervision of a Professional Engineer.
4.6.1 The project teams were furnished with block wall data forms and architectural drawings per Section 4.2.
They were instructed to fill out the forms for each wall and attach photographs of the as-built walls whenever practical. The copy of the form used for the field work is given as Attachment 2.
4.7 The field data of all disciplines were compiled in the office. Systems and equipment which could not be identified in the field were rechecked from the existing drawings.
4.9 Tables 6 through 9 provide lists of safety and non-safety related equip-ment for the walls identified in Tables 2 through 5, respectively. Table 6, for example, identifies equipment and piping for the walls listed in lable 2.
In addition, in Tables 6 through 9, piping and equipment which are attached to the walls are distinguished from those which are in the Q(N vicinity. A priority nunber is 'also assigned to the walls.
5.0 PRIORITIZATION OF WALLS 5.1 A safety evaluation report for all walls identified in Tables 2 through 5 will be transmitted to the Nuclear Regulatory Comission within 180 days from the date of IE-Bulletin No. 80-11.
5.2 The walls are prioritized in three basic groups based on relative safety classification of equipment. The Following criteria are used for as-signing priorities to the walls.
5.2.1 Priority I Systems required to bring the plant to a safe shutdown or to main-ta'.n i t in the safe shutdown condition.
See Table 1.1 for the sys-tems included in this group'.
5.2.2 Priority II Systems associated with the safety of olant personnel in term.s of radiation, service water, etc. See Table 11 for the system list.
5.2.3 Priority III r(),
All other safety design Class I systems are included in this group. See Table 1.1 for the system list.

RESPONSE TO IE BULLETIN 11 21-7450-280 Page 4 g
5.2.4 The relative priority of' walls in each priority group will be based on the number of safety systems attached to the walls.
Wells with multiple systems will have higher priority.
5.2.5 The priority of walls with equal number of safety related sys-tems will be fixed during re-evaluation stage based on the magni-tude of loads attached on the wall. Walls with heavy loads will be re-evaluated first.
5.3 Table 10 provides the list of walls included in each priority group.
l 6.0 RE-EVALUATION OF THE DESIGN 6.1 Walls identified in Tables 2 through 5, will be screened in accordance with the following criteria oefore stress analysis of wall is undertaken.
6.1.1 Compare loads recorded on the data sheets with the loads for which the walls were originally designed.
If additional loads were not added to the wall, then the wall will be considered to be safe and no further analysis will be done.
6.1.2 Loads of electrical conduits,1" and 1-1/2" diameter pipes, HVAC ducts, etc., which weigh less than 100 lbs. will not be considered.
v 6.1.3 The load of ducts and pipes which penetrate through the wall but are not directly supported by the walls will not be considered.
6.1.4 The walls which support additional new loads in excess of 100 lbs.
or do not meet construction acceptance criteria presented in Section 7 will be reevaluated.
7.0 RE-EVALUATION ACCEPTANCE CRITERI A 7.1 Types of Masonry Walls Masonry walls shall be classified as follows:

7.4.4.2 For local strength evaluation it will be conservatively assumed that only one wythe shall support the tensile loads nonnal to the walls.
7.4.4.3 If one wythe is not sufficient to support the tensile load then composite action (more than one wythe acting together) will be considered provided the tensile stresses between the wythes do not exceed 25 psi.
7.4.4.4 If a value greater than 25 psi is required to satisfy the composite behavior then justification will be given in (3
the form of accepted industry standards or test data.
V Otherwise, corrective action will be proposed.

RESPONSE TO IE BULLETIN 11 21-7450-280 Page 9 7.4.4.5 For overall bending of the wall the vertical shear transfer through the mortar between wythes will be calculated using formula VQ/IB.
'7.4.4.6 If the shear stress exceeds the allowable shear stress then each wythe will be considered separately.
The distribution of lateral loads shall be taken in propor-tior. to the relative stiffness of the wythe.
7.5 Allowable Stresses Allowable stresses for the masonry walls shall be as per Table 1 which conforms to ACI 531-79.
7.6 Codes and Documents The evaluation of the masonry walls shall be governed by the 1967 edition of the "Unifom Building Code (UBC) unless otherwise noted in this report or in the final safety analysis report (FSAR) for the Prairie Island Nuclear Plant.

In this phase safety related masonry walls will be cl$sified irl ac-cordance with their function, type of construction -(single or double wythe walls), reinforcement requirements and Quality.' Assurance re-quirements. The information in this phase will brobtained from the structural drawings released for construction of the walls and existing design calculations.
s 8.3.2 Review of Quality Assurance and Inspection Reports Quality Assurance and inspection records for the masonry walls will be examined and compared with the materials and construction methods specified.
Discrepancies found will be documented.

8.3.3 Re-evaluation of Priority I Walls 7
~
e Structural integrity and margins of safety for the walls in Priotity J
I will be investigated in this phase for the loads and load combi-nations proposed in the re-evaluation criteria. Both local and overall behaviors will be considered. Only those walls which are subjected to loads more than original design loads will be re-viewed. Walls which fail to meet re-evaluation acceptance criteria may be further. scrutinized for the actual values of loads and the analytical mode'l us'ad for computation of stresses.
Modifications either in the form of reduction of loads or strenathening of walls will be proposed'for walls found deficient.j N

5.0 PROJECT ADMINISTRATION (CONTINUED) 5.7 PROJECT SYSTEMS LIST - (PRAIRIE ISLAND ONLY) 5.7.1 Definitions In accordance with the requirements of the Project Management Department Procedures Guide, a project system list was developed for the original Prairie Island Project 21-6197 and modified for the Follow-On projects 21-7450. The system list begins on page 7 and contains:
- 5. 7.1.1 Column one - the system name.
5.7.1.2 Column two - the system alphabetic code; a unique com-bination of two or three letters which may be used at in place of the system name.
- 5. 7.1. 3 Column three - a list of the responsible disciplines for the system as follows:
Code Discipline A Engineering Support Services E Electrical I Instrumental & Control M Mechanical N Nuclear S Structural If more than one code letter is listed, the code letters will be separated by a slash (/). The first listed code letter has the lead responsibility. 5.7.1.4 Column four - the Quality Assurance (QA) Type are amplified in Appendix 8 of the FSAR. In addition, the Assurance Type for piping is further defined in Specification Hiawatha 106, (piping, fabrication, and erection) for the original Prairie Island Project. Any deviation from the definitions will be established on a project basis with the approval of the Project Manager. ceO r. V 0

QA Type I Those items for which the Quality Assurance Program must assure the highest feasible degree of quality standards consistent with the importance of the safety function to be performed. This category includes, in accordance with NRC Design Criterion No. I specified in 10 CFR 50, those items of the plant which are essential to the prevention of accidents which could affect the public health and safety by the release of substantial quantities of radioactivity or are required in the mitigation of the consequences of such accidents. QA Type II The items for which the Quality Assurance Program must engender a highly confidence level that the item will perform satisfactorily. This category [d s ') includes those items whose failure would not direct-ly affect the health and safety of the public but the failure of which could cause severe economic loss or cause the plant to experience an extended outage. QA Type III Those items for which there is no compelling need of a Quality Assurance Prcgram beyond that required to obtain good workmanship in manufacture and construction. This category includes all other items not included in Types I and II. 5.7.1.5 Column five - the design class description The definitions of design class are amplified in Appendix B of the FSAR: Class I Those structures and components including instruments R and controls whose failure might cause or increase A the severity of a loss-of-coolant accident or result in an uncontrolled release of substantial
- amounts
[h 8 A substantial amount of radioactivity is defined as that amount of (] x o radioactive material which would produce radiation levels at the ] site boundary in excess of 1% of levels specified in 10 CFR 100. k

Also those structures and components vital to safe shutdown and isolation of the reactor are included. Class II Those structures and components which are important to reactor operation but not essential to safe shutdown and isolation of the reactor and whose failure could not result in the release of substan-tial amounts of radioactivity. Class III Those structures and components which are not directly related to reactor operation er containment. Class I* Structures The design of Class I* Structures is similar to the h design of Class I structure for seismic only as D detailed in paragraph B.6.3 (a) (i) of the Prairie Island FSAR. In all other respects the design of Class I' Struc-tures is identifcal to the design of Class III Structures as detailed in paragraph B.6.3 (e) of the Prairies Island FSAR.
- 5. 7. 2 Modifications to the Existing Plant Systems.
Quality assurance type and design classification can ue deter-mined by referring to the existing plant documents such as flow diagrams, line list, or the FSAR es well as the following table.
- 5. 7. 3 Additions of Nev: Plant Systems For new systems which are added to the existing plant, the most current regulatory guides and criteria must be used.
Since it is desirable to maintain the original nomenclature and definitions used for the design and construction of Prairie lE Island, the quality assurance and design classification require-l 2 ments must be compared to the definitions stated previously. A substantial amount of radioactivity is defined as that amount of m radioactive material which would produce radiation levels at the sO site boundary in excess of 1% of levels specified in 10 CFR 100. 2m l
